3.4. HYDRAULIC SETTINGS
Your Vip'R2 damper features 2 hydraulic ways of settings:.
3.4.1. Compression
The compression setting offers two positions : «hard» et «soft».
The lever must be turned on one of these two positions, never between.
The soft position is used for normal riding conditions. The suspension is 100% efficient.
The hard position changes the whole compression curve. The shock becomes stiffer on all the travel. It has to be
used when you need better pedaling efficiency, while climbing, or on flat hi speed track sections.
WARNING
The hard position is not locking the shock out.
As for the TRC system featured on the Deville fork, it reduces the suspension moves, by stiffening it, but the
suspension remains efficient. A still efficient -although stiffer- suspension keep guaranting a good traction.
It’s also a safe option, in case of unexpected shocks.
The compression adjusted through the lever A.
The Rebound adjusted through the knob B
